East End
2019-05-31

I arrived about 12:00. It was clear sunny and hot. Kristen Maines from USGS is here with her crew flying their methane drone upwind of the tower. They started about 10am on the main midline road. A ditch digger was clearing the main drainage ditch near the north end of their transect so they were seeing elevated CH4 at that end. About 1pm they came to the tower and were planning to fly transect curtains (back and forth at different heights) near the edge of footprint upwind and downwind.

Before the drone crew arrived I collected the autocam images and miniDOT data that were missed last week. I put some silicone dielectric grease on the o-ring before redeploying the miniDOT.

The camera is a pain to deal with. I need to test the one in the lab more to see if I can make it easier to service. The CDHK that is running in the field should be on the field laptop.

About 1:30 just before they started flying near the tower I cleaned the 7700 mirrors. Before cleaning RSSI was 41 after it was about 80. Seemed to be a lot of pollen on the bottom mirror. I left soon after.
